DIYed XL 037 Belt pulleys for the 7 x 14" mini lathe.

[DIYSwede]

Well - started out this morning with the belt - pulley conversion - nothing dramatic:



Tore the old stuff away, suddenly realizing the length discrepancies between the new and old belt:



A new run of the old belt length formula:

Lp= Pitch length, A= Axle c-c (108 mm), Do= Large pulley pitch dia (48,5 mm), do= Small pulley pitch dia (16,17 mm)

Gave the value: 317 mm, which correponds to a 126 XL 037 belt (63 teeth)
(not a 210 XL, which I wrongly ordered 2 years ago).

Just happily placed another $13.50 order (incl free shipping) for 3 belts,
with the absolutly reasonable delivery window from 3 weeks 'til the end of May...''
That money can in three days get me one belt of the very same brand thru a national distributor, so I guess I'll just sit it out?
The same company would also kindly offer an aluminum 30T XL pulley (w/o flanges) for 55 bucks...
i.e. a 10 mm offcut from a 30T solid extrusion. Bargain!

Goes to show that I shouldn't have been so cock-sure when ordering the previous ones?
The Dunning-Kruger Effect still hits me hard from time to time, as we're all confident idiots at times.

My late grand-dad once told me in the wood shop: -"Measure 3 times, so you'll only need to cut once."

So - this project is temporarily on hold, "due to unforeseen human error"...
