I followed up with the local suppliers and the cost is substantial.flyingtpot wrote: ↑Wed Sep 09, 2020 4:52 pmHi Mal,
Oops.... I meant to include the Sunnen part numbers of their portable mandrel drivers for your review. The P-180 and P-200 are the units to use in this application. The initial upfront cost of the tooling usually is the reason not to take this process path. Yet, it is an excellent tooling approach to have available especially if you have other uses for it in your shop.
Now that high quality carbide reamers are readily available, and the norm in some speed shops, I've tapered off on some use of my Sunnen equipment while switching over to reamers. Yet, there are still times when stones are the path to take. The Honall and Sidewinder are not for large bores (over ~35mm).
Though it seems like an excellent product - I guess we have had our dollar values corrupted some what by cheap knock offs coming out of Asia.
The secret is what else could I use it for?
I thought I would get a price from an engineering shop to do this task for me and that will give me some idea of the relative merit of farming this task out. It may be the best end result.
Thanks for opening my eyes to this product.
