Not sure what procedure you are following, but I've had excellent results with my set doing following:

Drill first two holes at extremities of the stick (say 0 and 10) then insert pins.  At this point you need to be careful as you can introduce flex in the ruler, I clamp ruler very carefully and check that clamping does not flex or push the ruler.  Next drill center hole (5 in this example) add the third pin and from there drilling the other holes is straightforward.

If you are drilling 3mm holes from one end to the other (0 then 1, then 2 .....) then flex errors are more likely.  Hopefully nothing wrong with your kit.  Sorry, sounds like you were drilling a fairly finished panel that is now possibly spoiled?

Hi @Hollatime  and thanks to @AstroKeith

The biggest error that users of the Mark 2 PGS make is in registering the pins in the rulers. The pins have a 6 mm boss that fits (very) snugly in the ruler yet it is all too easy to think that the two are registered but are not.

In order to have a foolproof approach do the following. When trying to engage a pin in the ruler lift the ruler slightly and make sure that the 6 mm part of the pin really does engage in the 6 mm hole of the ruler. Then push the pin and ruler down together.

The tolerances are tight and when you first receive your Mark 2 you may need to use a twisting motion to get the engagement between pin and ruler the first few times.

It was a hard decision to have this 6 mm hole/boss approach but the key advantage is the super accuracy when drilling the 3 mm holes. The 3 mm guided drilling is spot on.

I am really grateful to Hans @TSO Products for the support that he is giving to the ever growing PGS community.

I am also pleased that Ron Paulk is now using the Mark 2 version for all of his custom bench tops.

Take care everyone and stay safe during this difficult time.

Peter

@Vtshopdog  @Peter Parfitt


I don’t think it’s an issue with locating the pins as it’s occurring in the very first set of 10mm holes. I’ve watched your video/do the whole register pin then push it+parf stick down etc.

VTshopdog. I do the same operation except never used the third pin. Drilling the last 2 test rows I left the sticks fully clamped the entire time. Always finish before just in case it effects the tolerance of the holes.  Annoying time wise for me but a ruined panel/scrap pretty common for me haha

Having an issue getting good results, ordered from Axminister roughly start of May this year so assumed the old issues were worked out. I reached out to support but guess they are closed through the weekend, and plenty of knowledgeable users here.

How much, if any play should be in the 3mm bushing?
The 3mm bushing will rock side to side and is a bit tippy, but hold it with a death grip. It will spin freely and can shift somewhat laterally without the tipping.

The bushing is 6mm for the MK 2 and is made for the 3mm drill.  Is this what you mean?

My Parf Guide MK 2 arrived last week from Axminster, but I didn't open it up until now because of the problems you are having with yours.  After I wiped all of the oil off of the components, I tried both of the 6mm bushings for drilling, the three 3mm pins with 6mm shoulder, and the 6mm joining screw.  Everything fit snuggly in the rail holes and I could not move them side to side at all.  With both rails joined, all of the holes line up as perfectly as I can see and everything is solid with no movement at all.


Made sure to try to tap the straight edges straight and what not since the pins are curved, again try hard mode engaged for sure.

This has me really confused.  What are you tapping to straighten and which pins are curved?

The 6mm bushing, non-spigoted one is the one I am referring to. I haven't tested the joining screw, the spigoted bushing seems like a closer fit than the non.

I am trying to determine if the holes I have drilled are straight. After drilling a row of 3mm holes, I removed the parf stick and inserted the 3mm pins with 6mm shoulders into a variety of the holes and checked it with a straight edge

There is no bushing without a spigot in the MK 2 kit.  One has a short spigot, or shoulder, for use with one rail and the other has a longer spigot for use where two rails intersect.  If you have a bushing without a spigot, then this might be the problem.

Correct. I would be referring to the one with the shorter spigot

Following up on my earlier issues.

I'm pretty dissapointed with Axminster and the Parf Guide MKII. I reached out with my initial issues, and had to check in practically every day with CS for over 2 weeks until they finally shipped replacement parf sticks and the small spigot drill bushing. It was also sent  through a budget carrier/not the typical DHL awesomeness.

I am almost certain it is not user error at this point. I follow protocol as if I was disarming a nuclear warhead. I've tried different drills, I've legit made 10 or so attempts and none of them have worked out.

The only thing I could think of at this point aside from another set of bunk sticks is the orange 20mm jig doesnt lay entirely flat, but I assumed that was due to the dust port/hose. I use all 3 pins whenever possible to secure/locate the jig and hold it with my hand down as well.

Considering my prior experience with  Axminster's CS, I'm not really interested in waiting another 3 weeks just to again waste more time and materials on this system. The QC just isn't there I suppose, or I am just an absolute stone idiot.

I've recently raised enough funds to invest and I am considering the Parf Guide Mark II System.

Any progress since last post?

I see there is a shipment due in 2 weeks.
41 coming in and 2 on back order.

Any suggestions to wait or not?

Hi Everyone

There are two videos that will help. The first is quite long but it gives the step by step instructions for building a tracksaw cutting station and includes me pointing out common errors that are the most likely cause of a disappointing result:



After that went up a number of viewers asked me to show the 5 cut test (also know as a 4 cut test if you have one good side at the start).
