Description

Description:

This is a jig to mark and drill holes to make an MFT bench dog work bench. The alignment dogs include both a fully rounded and half round portion allowing them to be used to reference off of previously drilled holes or off of the tables edge. There is also a marking dog tool that can be used to mark or punch the centers of the holes to be drilled. I used this with a transfer punch to help prevent the drill bit from walking. Ignore the color change in the display photos. I just ran out of black part way through the print.

Other Tools Required:

Drill
Drill bit

Other tools recommended:

Center Punch

Replacing the surface top of my workbench in the next few weeks and I am looking forward to an accurate dog hole layout now. Thanks for sharing!

Love the color combo.

I'm not sure why the dogs aren't fitting all the way. I printed the 20mm version. I know I had an issue the last 1.5 hours with an extruder error I rushed but the dog holes should still be able to fit all the way through right?

@user_501593334

They were designed to be tight. I worked mine in and out a few times to wear them in.

@user_334003810

Replying to @user_501593334 :

Okay, thank you for the reply. I'll try and work them in.

@user_334003810

edit: after VERY minimal sanding on the dogs, they slide in perfectly. looking forward to using this soon. Thank you!

@Macaus

Tried this out and it definitely works as advertised. The hole spacing was a bit closer than I wanted for the 20mm holes, just my preference as I felt the holes were either to close or far with this jig, but other than that a top notch effort. The holes reamed out easily using the 20mm bit and a drill press, for squareness. May I suggest that a guide for a 100mm by 3.75mm Pasload nail, or similar, be included that could be used like a centre punch for the hole locations. Would allow for a little more flexibility in hole size for other uses. I am actually thinking of this variation for an assembly table.

I went with the standard spacing for MFTs.

Did not turn out right. The pegs printed with this didn't fit in the holes. None of my 3/4" bench dogs would fit in this either. 3/4" drill bit wouldn't fit.

Interesting. I haven't had or heard of any other problems. Is it possible that the scaling was altered?

@mattstache

Replying to @user_501593334 :

I did not touch any settings. I simply loaded, chose filament and printed.

@user_501593334

Replying to @mattstache :

Was it just a little tight? It is meant to be tight for max accuracy. With mine the dogs fit but they took some effort which lessened as I worked them in and out. The drill bit also fit but had to be aligned perfectly. Of course the bit can also be used to create the perfect sized hole.

@Bunti

A truly superb template! It printed flawlessly on the A1 in PETG using the standard settings. The only change I made was increasing the wall count to 4. A few tips:Invest in a high-quality 20mm Forstner bit (e.g., from Fisch or FAMAG). it makes the whole process much easier! I printed an additional vacuum attachment (https://makerworld.com/de/models/776717-40mm-vacuum-hose-holder-mft-20mm-dog-holes#profileId-729372) for my setup to suck up the wood chips. Otherwise, they tend to clog the drill hole.

Nice print and functionality. When you take time to place jig, then it gives a very good result.

Hot off the plate. will be testing it later today to do a dry run before I do a full top. Will be using a 8mm brad point but with a straight hole jig to ensure precision.

@it_really_is_me

I am just about to try this. I was thinking of changing wall order from inner/outer to outer/inner to see if that helps with fit. Is that worth trying?

The designer has replied

@user_501593334

Not sure. Could be worth a shot.

@it_really_is_me

Replying to @user_501593334 :

It does seem to make a slight difference. Could be the difference between a snug fit and no fit. I would recommend people use the cut function to reduce and test how it works out before printing the whole thing.

@FullNameHere

Replying to @it_really_is_me :

Outer then inner wall results in the overfill being inside the object instead of outside the object so it's more likely to be dimensionally accurate.

@Nopo

Turned out great A1 add:north petg

@Rafa3ll4

Very nice print! Looks more solid than I was expecting. I’m wondering which router you used to drill the holes? Thank you

I used a woodowl drill bit and my drill.
