Transfer Screws--Making and Using-Pics

[sandman2234]

I used one of my 5 beam lazers transferring a dozen bolt locations (for a skid plate) under the tractor to the concrete shop floor and marked the floor with a pencil. Then it was just careful measuring on the actual 1/4" plate, it worked like a dream!

Just wondering... why didn't you just drive the tractor over the plate, measure the plate to be square with the tractor, and mark the plate with the laser, using a marker (or a center punch). That way no chance of miss measuring the holes and getting the plate incorrect.

I use transfer screws all the time at work; very handy. The advantage is that they pick up on the thread centers whereas the rubbing and other methods pick out the malformed circle as the thread asymmetrically breaches the plane of the part. If you want to be within say 0.010", transfer screws are the way to go.

Question for the OP, are yours hardened? Nice job!

I totally agree with this.
Tractor work typically is with 1/8 to 1/4 inch is close enough, but when making parts for most industries, using that range will make a lot of scrap parts! Shop I worked in for a while had to be temperature controlled building due to the .0005 tolerance on a couple of parts.

If you have the other part that matches to the bolt holes you can use a transfer punch to locate the holes on your new part. Less possibility for slippage if you clamp the parts together. I have punches from 1/8 to 1". Bought on Amazon.
